I wouldn't want Hiddink and I don't think he would want us. It's a long time since he spent any extended time in top club management and he seems to prefer picking up huge pay cheques in jobs where there is not much pressure to succeed. In any case, ignoring the Anzhi farce, his last two jobs ended with Russia and Turkey ended in failure. In essence, I think his reputation greatly exceeds his actual achievements, certainly in recent years.
Totally agree on Jose though (assuming we didn't actually try to get him) - the manager that is most like Fergie in substance. Instead, we got a man with some superficial similarities to Fergie but without the key attributes (proven winner, ability to handle big names, experience in managing all the expectations and pressues of a big club).
